Sporadic variety of pallido-pyramidal syndrome.

ABSTRACT

A rare case of a 40-year-old lady with a sporadic variety of the pallido-pyramidal syndrome (PPS) is reported. She had marked parkinsonian features on the left side. Her single photon emission computed tomography showed left frontoparietal and basal ganglia hypoperfusion. CT scan and central motor conduction time were normal. She responded partially to a combination of trihexyphenydil and L dopa/C dopa therapy. In view of the diversity in the genetic, clinical and laboratory features, it is possible that PPS may be a heterogeneous condition.
